Study on Seroprevalence of Canine Visceral Leishmaniasis (CVL) in Ownership Dogs of Sarab, East Azerbaijan, Province, Northwest of Iran with Indirect Immuno Fluorescence Antibody Test (IFAT) and its Health Importance in 2008-2009
چکیده
This study was made to investigate the seroprevalence of Zoonotic Visceral Leishmaniasis (ZVL) among the ownership dogs of villages in Sarab city and to find the possible relationship between to transmit of parasite from infected dogs to human beings. In this study blood sampling was made from 384 ownership dogs for recognizing seroprevalence of visceral Leishmaniasis with Indirect Immuno Fluorescence Antibody Test (IFAT). The serum was conjugated with anti leishmania infantom IgG antibodies and examined with fluorescent microscope. The seropervalence values among male and female animal were 9.2 and 6.5, respectively. Sero-Prevalence Rate (SPR) of CVL among ownership dogs in Sarab was 8.5% however, considering the cut off degree (1:80) from 384 dog 33 dogs of them was positive serum on the basis of anti L. infantom IgG antibodies. In this study, the antibody titer in male dogs was more than that of female dogs, however, it was not statistically significant (p = 0.023). The highest infection was found in dogs of jaldabakhan village 29.6% (8) and the lowest infection was found in khaki 3.3% (1). In this study only in Asbfroshan and Jaldabakhan areas 2 dogs had antibody 1:40, which was a negative serum antibody. There was statistically a significant difference between male and female infection to Visceral Leishmaniasis (p = 0.962). Considering the different animal reservoirs and various geographical animal conditions in this area and regarding the zooonotic parasite, controlling the animal reservoirs seems unavoidable and fighting against the vector sand fly and controlling plans are necessary.
